摘要
Background The primary care specialist interface is a key organisational feature of many health care systems. Patients are referred to specialist care when investigation or therapeutic options are exhausted in primary care and more specialised care is needed. Referral has considerable implications for patients, the health care system and health care costs. There is considerable evidence that the referral processes can be improved. Objectives To estimate the effectiveness and ef fi ciency of interventions to change outpatient referral rates or improve outpatient referral appropriateness. Search strategy We conducted electronic searches of the Cochrane Effective Practice and Organisation of Care ( EPOC) group specialised register ( developed through extensive searches of MEDLINE, EMBASE, Healthstar and the Cochrane Library) ( February 2002) and the National Research Register. Selection criteria Randomised controlled trials, controlled clinical trials, controlled before and after studies and interrupted time series of interventions to change or improve outpatient referrals. Participants were primary care physicians. The outcomes were objectively measured provider performance or health outcomes. Data collection and analysis Two reviewers independently extracted data and assessed study quality. Main results Seventeen studies involving 23 separate comparisons were included. Nine studies ( 14 comparisons) evaluated professional educational interventions. Ineffective strategies included: passive dissemination of local referral guidelines ( two studies), feedback of referral rates ( one study) and discussion with an independent medical adviser ( one study). Generally effective strategies included dissemination of guidelines with structured referral sheets ( four out of fi ve studies) and involvement of consultants in educational activities ( two out of three studies). Three studies evaluated organisational interventions ( patient management by family physicians compared to general internists, attachment of a physiotherapist to general practices and requiring a second ' in- house' opinion prior to referral), all of which were effective. Five studies ( six comparisons) evaluated fi nancial interventions. Two studies evaluating change from a capitation based to mixed capitation and fee- for- service system and from a fee- for- service to a capitation based system ( with an element of risk sharing for secondary care services) observed a reduction in referral rates. Modest reductions in referral rates of uncertain signi fi cance were observed following the introduction of the general practice fundholding scheme in the United Kingdom ( UK). One study evaluating the effect of providing access to private specialists demonstrated an increase in the proportion of patients referred to specialist services but no overall effect on referral rates. Authors' conclusions There are a limited number of rigorous evaluations to base policy on. Active local educational interventions involving secondary care specialists and structured referral sheets are the only interventions shown to impact on referral rates based on current evidence. The effects of 'in- house' second opinion and other intermediate primary care based alternatives to outpatient referral appear promising.
